at quinns popcorn stand, customers can scoop their own popcorn and pay by the ounce. ten ounces of popcorn costs $2.50. write two different equations that represent this situation. use p for ounces of popcorn and c for cost in dollars.

Answer

Explanation:

Step1: Find the unit - rate

The cost per ounce is found by dividing the total cost by the number of ounces. Given that 10 ounces cost $2.50, the cost per ounce $r=\frac{2.50}{10}=0.25$ dollars per ounce.

Step2: First equation

Since the cost $c$ is the product of the number of ounces $p$ and the cost per ounce, the first equation is $c = 0.25p$.

Step3: Second equation

We can also write the equation in the form of $p=\frac{c}{0.25}$ because $p=\frac{c}{r}$ (where $r$ is the unit - rate).

Answer:

$c = 0.25p$ $p=\frac{c}{0.25}$
